Urban dengue is common in most countries of the Americas, but has been rare in the United States for more than half a century. In 1999 we investigated an outbreak of the disease that affected Nuevo Laredo, Tamaulipas, Mexico, and Laredo, Texas, United States, contiguous cities that straddle the international border. The incidence of recent cases, indicated(More)
Isolates of Borrelia turicatae, Borrelia parkeri, and the Florida canine borrelia (FCB) were examined to further phylogenetically characterize the identities of these spirochetes in the United States. DNA sequences of four chromosomal loci (the 16S rRNA gene, flaB, gyrB, and glpQ) were determined for eight isolates of B. turicatae and six isolates of B.(More)
Hantaviruses are etiologic agents of hemorrhagic fever with renal syndrome, an acute illness characterized by acute renal insufficiency, proteinuria, and hemodynamic instability. Recently, a New World form of hantavirus disease, hantavirus pulmonary syndrome (HPS), was recognized; in this form, pulmonary edema is prominent, but renal insufficiency is(More)
An environmental and laboratory investigation was conducted after a fatal childhood case of hantavirus pulmonary syndrome occurred in Deaf Smith County, Texas in May 1995. A trapping campaign was conducted to identify possible rodent carriers. Six species of murid and heteromyid rodents were collected, and at least one hantavirus-seropositive specimen was(More)
The Texas Department of Health Laboratory cultured arthropods from November 1988 through December 1989 in an attempt to isolate Borrelia burgdorferi, the etiologic agent of Lyme disease. Spirochetes were isolated from eight of 1,093 pools of arthropods cultured. The spirochetal isolates were from several tick and one flea species, including Amblyomma(More)
Tick-borne relapsing fever (TBRF), a disease of humans and other animals, has been recognized in North America since early in this century. Caused by Borrelia spirochetes, TBRF is transmitted by softshelled Ornithodoros ticks, which may also act as reservoirs for the etiologic agents. Initial symptoms include sudden onset of fever, chills, headache,(More)
In 1997, the Centers for Disease Control and Prevention, the Mexican Secretariat of Health, and border health officials began the development of the Border Infectious Disease Surveillance (BIDS) project, a surveillance system for infectious diseases along the U.S.-Mexico border. During a 3-year period, a binational team implemented an active, sentinel(More)
Dengue epidemics have been occurring in the Caribbean and Central and South America, including Mexico. In 1995, the proximity of these epidemics increased the possibility of cases occurring in Texas. In response, medical and community educational materials were distributed and active surveillance for dengue cases was initiated. By the end of the year, sera(More)
